surface plasmon??
hi
Can anyone explain to me what's the surface plasmon?
thanks

Surface plasmon is a phenomenon in which light waves interact with the free electrons on the surface of a metal, resulting in the creation of a collective oscillation of the electrons known as a plasmon.
Surface plasmon resonance occurs when a light wave, known as the incident wave, hits the metal surface at a specific angle, called the resonance angle. This causes the free electrons on the metal surface to oscillate, leading to the formation of a plasmon wave.
Surface plasmon has various applications in fields such as biosensing, optoelectronics, and nanotechnology. It is used in biosensors to detect and measure biomolecules, in plasmonic devices for data transmission, and in nanoscale devices for enhancing light-matter interactions.
Surface plasmon-based biosensors have several advantages, including high sensitivity, real-time detection, and label-free detection. They also require small sample volumes and can be easily integrated into portable devices for on-site testing.
In optoelectronics, surface plasmon is used to manipulate light at the nanoscale level. It can be used to control the propagation, absorption, and scattering of light, making it a promising technology for developing advanced optical devices such as solar cells, LEDs, and photodetectors.
